Yeah a one internationsl/invitational is a good idea, but I dont think queue jumping in a National is fair. I'm new to things but the impression I get is there aren't that many races annually, and a lot of people really look forward to an opportunity to race. Take their chance away to allow a few top guys a place and your making your hobby/sport elitist. These guys get plenty of racing in all over the world, whereas Joe Bloggs works his nuts off all year and maybe gets the chance to race at a decent level only 4 or 5 times.
I can see your point, its good to see high profile racers, I just think you'd have to be careful not to be unfair or alienate the real people that keep the scene going.
Power to the common man yeah. Right on baby!
